WOOD most common form of biomass—renewable Pros: · burned for heating and cooking · In the United States, wood and wood waste (bark, sawdust, wood chips, and wood scrap) provide about 2% of the energy we use today. · Produces 90% less carbon dioxide when burning compared to fossil fuels Cons: · causes pollutions when burning · provides less energy than coal · cutting down the trees leads to less air 2 Uses: · Generates heat · Generates electricity
HYDROPOWER
power that is derived from the force or energy of moving water, which may be harnessed for useful purposes—renewable Pros: · controls flooding and provides recreational activities such as boating fishing and swimming · inexpensive repairs and malignance costs · in case of drought dams still will have a relatively constant supply of water Cons: · disrupts natural seasonal changes in the river--ecosystem can be destroyed · produces as many greenhouse gasses as more conventional methods of producing electricity · expensive to build 2 Uses: · Provide irrigation and flood control · Energy for electricity
OIL Nonrenewable Pros: · reliable electricity produced · easier to store, transport, and burn than coal · most versatile fossil fuel Cons: · takes millions of years to form · causes greenhouse gasses · many products obtained from oil are highly toxic 2 Uses: · generates electricity · generates heat
GEOTHERMAL Generated by heat stored beneath the Earth’s surface—renewable Pros: · Low heating cost · Uses less electricity to produce same amount of heat · Low levels of air pollution and greenhouse gases Cons: · Very high installation cost · Coal based electricity, is not ecologically acceptable fuel since it releases carbon dioxide · Causes global warming 2 Uses: · Helps grow crops · Pasteurizes milk
COAL Nonrenewable Pros: · One of the most abundant sources · Relatively inexpensive · Produces useful by-products Cons: · Emits harmful waste such as carbon dioxide, sulphur dioxide, nitrogen oxides, sulphuric acids, arsenic, and ash · Coal mining can scar the landscape and equipment used for mining is large and noisy which can affect local wildlife · There are limited stocks of coal remaining 2 Uses: · generates heat · used to generate power plants
